SUPPORTING BASE FOR CURRENT CGNDUCTORS.

Application filed April 4 celain, and to construct said ha so that the currentconductor may be suitably strung thereon quite rapidly, so as to produce various designs, and in the following specification I shall disclose my form of con struction, and the manner in which the current-conductor is strung to produce a particular design, and What I claim as new will be set forth in the claims forming part of this specification.

Fig. l is a front elevation of my sup porting base showing strung thereon the current-conductor. This view also shows my supportin base as provided with mounting means. *ig. 2 is a vertical cross-section on the line 22, Fig. 1.

in the drawings like characters of reference refer to the same parts.

My base may be used for mounting a currentconductiin: wire er filament, of any desired term, and for any purpose in the electrical art, though in the disclosure made I use the base as a. support for a resistor or heating element to be used in connection With electrical heating-and-ceeking appliances.

A is the base, and countersunk in opposing edges thereof, are recesses D. the shape of which may vary. The formation of each of the said recesses provides a post or pin 0 which is laterally spaced apart from the sides of said recesses by means of the open slots 13 which open through to the face, or front side of the base. Each post or pin C is slotted as at E at the base there of, and in its rear side to receive the loop F of the current-conducting element G.

1922. Serial No. stasis.

Upon inspe-rti q served that the cur G is strung over tl A. by means of the posts or pins and that this is a quick method oi associating the said elements.

f course the binding nests for the rent-conducting element d may be of any desired character, and may be suitably located. H are conventional binding posts preferably countersunk in the front face of the base A by means of recesses Gr.

I any suitable mounting means for the base A; this mounting means new or may not be used, depending entirely upon the field of use of the article.

The posts or pins C in the example of in base, are located in staggered positions in opposite edges of the base. This location Fig. 1, it will be ob- 3I1il-COI1ClllC't-1Dg element iront face oi the base of said posts will enable me to string the current-conducting element G in place and obtain the desired design.

The posts or pins C are located at one end of the recesses D adjacent the "front face or side of the base A and so proportioned that the loops F will not be longer than desired.

Since the posts or pins C do not project beyond their associated edges of the base A, it will be understood that a number of these bases may be placed one upon the other, and edge to edge, and build up, for example, a backing; for various types of grates.

\Vhat I claim is:

As a new article of manufacture, sup-- porting base provided with a plurality of spaced recesses in opposite edges thereof extendingthrough from one side of the base to the other to term a post or pin at one end of each reces which posts or pins are located to be flush each with its associated edge of said base and the face thereof, and each of which. is narrower in Width than the width of its associated recess thus spacing each post or pin at each side apart from the adjacent Wall of its recess, each post or pin being provided 111 its rear side with a slot.
